Aussie vet stays abreast in Antarctica

It's not a new sport at the upcoming Sochi Winter Olympics, but what adventurer Geoff Wilson used to cross Antarctica.

Made out of Kevlar, the custom-built pink sled features an upscaled mould of Wilson's wife's breasts and held his supplies for the Pink Polar Expedition.

"Mentally they were a companion," the 43-year-old said on Thursday.

The Gold Coast-based veterinarian is the first Australian to cross Antarctica coast to coast, solo and unsupported.

His journey of 3428.53km took 53 days of kiting, skiing and trekking, and is the fastest anyone has traversed the continent this way.

Wilson said it was the cancer experience of a close friend, journalist Kate Carlyle, that inspired him to promote breast awareness and raise funds for the McGrath Foundation.

"There were multiple times when I hit a dead end and felt that I physically couldn't go on.

"Katie has had to walk this road, and the road's not over yet."

President and co-founder of the McGrath Foundation, cricketer Glenn McGrath, said Wilson's determination to support families touched by breast cancer is symbolic of the support he and his late wife Jane received.

"I think it's incredible. I think that's what life is about, to see that love and support," he said.

"You can go through things by yourself, but you're never alone, like Geoff was on the ice."
